The invention provides a rotary transformer testing tool based on a high-precision turntable, which belongs to the technical field of rotary transformer performance detection. The device includes a mandrel, a high-precision turntable, a base, a measured resolver, a stator tooling, and an adapter plate. The stator of the measured resolver is installed on the stator tooling, and the rotor is installed on the mandrel. The elastic bushing is fixed on the stepped table inside the tooling, the high-precision turntable fixes the mandrel on the base, the mandrel passes through the inner hole of the high-precision turntable, and the stator tooling and the high-precision turntable are connected through an adapter plate. The test fixture can be adapted to test the performance indicators of resolvers of different sizes. The characteristic of this test tool is that it can strictly guarantee the coaxiality and center height error of the resolver under test, and it is also easy to disassemble and assemble.
Description
technical field [0001] The invention relates to the technical field of rotary transformer performance detection, in particular to a rotary transformer testing tool based on a high-precision turntable. Background technique [0002] Resolver ("resolver" for short), as a high-precision angular displacement sensor, is widely used in various fields, and is mainly used to measure the rotational speed and angular position of the shaft. Compared with grating-type and Hall element-type sensors, the resolver has the characteristics of higher resolution, low cost, and wide environmental adaptability. It plays a key role in the feedback of the shaft angle position and speed in the whole machine system. Therefore, the accuracy and precision grade of its technical parameters directly affect the performance and reliability of the whole machine system. [0003] For the detection of resolver products, the traditional method is to fix the resolver on a mechanical indexer, find the voltage ze...
